SPBAY'ER-PUMP STRUCTURE.

Application. filed; March 26, 1923-.

To all whom it may concern:

Be it known that I, HENRY E. BnA vD'r, a citizen of the United States, residing at North St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Sprayer- Pump Structures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others. skilled in the art to which it appertains to make and use the same.

This invention relates to aclosure device for a receptacle, and particularly to a device for closing a sprayer receptacle and carrying means co-operating with a pump cylinder and plunger rod usually used in such receptacles. Such spraying devices, are now extensively used by gardeners, horiculturalists and other persons and usually comprise a closed receptacle having therein a pump cylinder plunger and plunger rod by which the liquid in the recepacle is placed under pressure. The plunger rod is provided with. an operating handle and this handle is sometimes used to carry the receptacle.

It is an object of this invention to provide a closure member for the sprayer receptacle which co-operates with the pump cylinder and plunger rod ina. simple, novel and eflicient manner.

It is a further object of the invention to provide such a closure member having two externally threaded portions, one of which co-operates with a threaded opening in the receptacle, the other of which co-operates with the threaded interior upper end of'the pump cylinder, said closure member acting to close both the opening in the receptacle and the opening in the pump cylinder.

It is. another object of the invention to provide such a closure member of hollow cylindrical form having an inwardly projecting lug disposed above the bottom of its interior and to provide a plunger rod having means thereon adapted to rotate beneath said lug.

It is more specifically an object of the invention to provide such a closure member having a shouldered recess therein andhaving an inwardly projecting lug punched out' or struck up from the lower port on of the' recess and spaced from the bottom thereof, together with a plunger rod reciprocable through the bottom of the closure member having a flange adapted to rotate beneath Serial. No. 627,567.

said lug with-means thereon to contact either side of said: lug and a recess therein to pass over saidlugr It is still another object of the invention to provide such a closure member having externally threaded portions". of different diameter, thereby forming a shoulder, the smaller of which portions receives the pump cylinder, the upper end: of which contacts with said shoulder, the larger diameter of the closure member fitting the threaded,

opening of-the receptacle and the said shoulder contacting a closing gasket therein.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the same part throughoutithe different views, and in which, I

Fig. l isv a view partly in side elevation and partly in section of a. portion of the upper end of a sprayer receptacle;

Fig. 2 is a View in vertical section, taken substantially on the line 22 of Fig. 1-, as indicated by the arrows F ig, 3 is a horizontal section taken on the line 3-3 of Fig. 2, as'indicated by the arrows;

Fig. 4 is a view in'side elevationof'the closure member; and a F ig. 5 is a view in vertical section thereof taken on the line 55 of Fig. 4;, as indicated by the arrows.

Referring-to: the drawings, a portion of a sprayer receptacle 1 is illustrated which receptacle is shown. as of the cylindrical: type having a vertical axis, although it is 'ob-. vious that this receptacle may be of any shape desired. Said receptacle is provided with an opening upon its upper end surrounded by a flange 2,111 which is seated and secured by brazing, soldering, o-rotherwise, a member 3 of substantially cylindrical shape, open at its top. and interiorly threaded. The said member 3 has a flang'eA; extending inwardly at its bottom portion on which seats a gasket member 4*, saidflange 4 having a central aperture therethrough in which. is disposed and adapted to pass, a pump cylinder 5.

A closure member indicated as whole'as; 6 is provided and comprises a hollow cylin drical member having comparatively thin walls which, as illustrated, has a portion '7 with a threaded exterior and a smaller porportion 8 and this lug projects inwardly from the interior wall of said closure member substantially in line with the shoulder between the portions 7 and 8. An opening through the side wall of the member 8 is thus formed by said struck-up lug, as clearly indicated in Figs. 4 and 5.

A pump plunger rod 13 is adapted to recipro-cate through the opening 10 and this rod carries at its upper end an operating handle 14 having at its lower portion in which the rod 13 is secured, a flange 15, which flange is provided at one side with a recess or cut-out portion 16 of a size and shape adapted to pass over the lug or tongue 12. Said flange also has upstanding at another portion thereof, shown as disposed opposite to the recess 16, a lug 17. It will be seen that the flange 15 is adapted to seat in the bottom of the member 6 and rotate beneath the tongue 12 and that the lug 17 will contact with the sides of said lug as the flange, plunger and handle are rotated in one direction or the other. The pump cylinder 5 is formed with an outwardly turnedclosed. The portion 7 of the closure member.

6 is, as clearly shown in Figs. 1 and2, adaptedto be screwed into the member 3 so that the shoulder below the same or the outeredge of the flange at the top of the cylinder .5 or both contact with the gasket 4 to form a tight seal and closure for the receptacle 1.

With the described structure, it is clear that when it is desired to operate the pump com rising the cylinder 5, the plunger rod can e turned by handle 14 to bring the recess 16 in alinement with the lug 12 so that the rod can then be'reciprocated as desired to operate the pump. When the flange 15 is turned and disposed below the lug 12, the receptacle may, if desired, be lifted and carried by the handle 14, the flange then contacting the bottom of said lug. If it is desired to remove the pump cylinder the flange 15 is rotated beneath the lug 12 by the hanthe lug 17 will then contact the side of lug 12 and the closure member 16 will be screwed out of member 3. The pump cylinder, together with the closure member 6 can then be withdrawn from the receptacle. If it is desired to have access to the inside of the pump cylinder, the same can be held in one hand and the handle 14 again turned in a counter-clockwise direction and the lug 17 Will then contact the sides of lug 12 and the closure member 6 will be screwed out of the pump cylinder 5. It is thus seen that the handle 14 not only serves to operate the pump and if desired, at times to lift the receptacle, but also forms a means by which both the portion 7 and the portion 8 can be turned and unscrewed from their respective parts. It is obvious that the members 6 can be again screwed into the pump cylinder 5 and into the member 3 by a clockwise turning of the handle 14 when the lug 17 has contact with the other side of lug 12 and turns the member 6 sothat it can be readily screwed into place.

F mm the above description it is apparent that applicant has provided a simple and efficient closure structure for a spraying receptacle. The closure member 6 is preferably formed by being pressed in a die and the tongue 9 punched out from the side thereof, as described. This member can thus be very quickly and inexpensively made. As indicated, the opening formed in the member 8 is no disadvantage as the same is closed when the member 6 is screwed into the pump cylinder. The handle portion 14 is also quite simple and, as described, accomplishes several functions which heretofore have been performed by different members and have been performed with difliculty and inconvenience. With applicants structure it is a simple and easy matter to disassemble the various parts and to reassemble the same and this advantage is attained by a structure which is simpler and more economical'than the structures of the prior art. The parts are' preferably made of brass, bronze or some other non corrosive metal as the spraying solutions sometimes used are quite corrodingv to certain types of metals. Applicant has, the'refore,-provided a simple novel apparatus and method of constructing the same and the success of the device has been amply demonstrated in actual practice.

I It will, of course, be understood that various changes may be made in the form, details and proportions of the parts andin the sequence of the steps of themethod without departing from the scope of applicants invention, which, generally stated, consists in the matter shown and described andset forth in the appended claims.
